Check Digit Verification of cas no

The CAS Registry Mumber 18651-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,5 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18651-17:
(7*1)+(6*8)+(5*6)+(4*5)+(3*1)+(2*1)+(1*7)=117
117 % 10 = 7
So 18651-17-7 is a valid CAS Registry Number.

Base catalysed Isomerisation of 3-Benzylidene-4-chromanones: Formation of 3-Methylflavones

Jain, A. C.,Sharma, Anita,Singh, Bikram

, p. 759 - 761 (2007/10/02)

3-Benzylidene-4-chromanones having even 7-methoxy- or 7-benzyloxy-group undergo isomerisation in the presence of alkali to give the corresponding 3-methylflavones besides the normal 3-benzylchromones.This observation differs from that made by Donelly et a
